Title: Separation equipment
Inventor: PRICE JAMES STANLEY
IPC: A01K67/033
Filed: 1984-12-21
Abstract: An apparatus 10 for separating worms from a worm-containing medium comprises two overlapping belts 12, 18. The medium is loaded on to the belt 12 from a hopper 14 which then passes over a heater 20. The heater raises the surface temperature of belt 12 to a temperature in which the worms experience sufficient discomfort for them to move upward on to belt 18. A scraper 22 removes the worms from belt 18 for collection in a first bin 24 while the substantially worm-free material remaining on belt 12 is discharged into a second bin 26. In an alternative embodiment the worm-containing medium is housed in a container heated to provide in the medium an upwardly-moving temperature front of 30 DEG C before which the worms flee. At the upper surface of the medium, the fleeing worms pass through a mesh-type or fabric covering from whence they can be readily collected en masse. <IMAGE>

Title: Correction for non-linearity in braking
Inventor: WICKHAM DAVID JOHN
IPC: B60T13/74
Filed: 1985-07-22
Abstract: A railway vehicle brake actuator employs an electric motor driving through a step-down gearbox to mechanically move the brake blocks. After the initial rubbing contact point the response of the system is non-linear and the motor feedback control involves compensation for said non-linearity. The motor output shaft is connected to a rotary shaft encoder so that the position of the actuator output member, and thus also the brake force applied, can be determined by pulse counting. The ideal relationship between a brake demand signal and brake force is linear. The actual relationship between actuator position and brake force is non-linear. Correction factors covering the whole operating range are stored in a memory against pulse count numbers and used as a look-up table in the feedback circuit to compensate either the feedback signal or the demand signal for the non-linearity of the response. <IMAGE>

Title: Gearbox having shift actuated by resilient means
Inventor: LANGLEY PAUL ARNOLD
IPC: F16H61/28
Filed: 1987-07-28
Abstract: It has been proposed to employ a constant mesh gearbox of the kind having pairs of gears on parallel shafts (1, 2) in constant mesh with each other, together with a clutch, in an automatic vehicle transmission. A microprocessor controls actuators for the clutch and throttle and hydraulic actuators for moving the selector rod (3) of the gearbox, in order to give automatic operation of the gearbox. In accordance with the invention, a constant mesh gearbox of the kind referred to is provided with actuating means (6, 9) for moving the selector shaft (3) and, in at least one direction of travel of the selector rod (3), the actuating means acts via resilient means which is arranged to store the energy of the actuating means when the actuating means is operated but the selector rod is not free to move, the rod being moved by the energised resilient means when the selector rod becomes free. More rapid shifting, and when the gearbox forms part of an automatic transmission, a shorter period of interruption of power, is possible, and reversal of torque during a gearshift can also be avoided.

Title: A method and an apparatus for controlling stress in a member and a fastener having stress indicating means
Inventor: BAN KEISUKE
IPC: B25B23/147
Filed: 1987-12-24
Abstract: In a method and an apparatus for controlling stress applied to a fastener member 1 or the like by a fastening tool 5 an elastic wave generated in the member is detected as the stress, for instance in the form of an axial force, is applied thereto and the fastening tool is activated according to the detection results e.g. to stop a motor 6 driving the tool. Since the elastic wave or the acoustic emission accurately reflects the internal state of stress in the fastener member 1, a very precise control of the stress in the fastener member is made possible. If a plurality of vibration sensors 7a are used, an exact identification of the source of elastic wave can be made and the measurement accuracy can be improved. In another arrangement, an indicator member having a property to emit a pronounced elastic wave is attached to the fastener and it is possible to freely adjust the target axial force as desired. The sensors may alternatively be attached to the fastening tool 5 as at 7' or on to one of the members being fastened, as at 7''.
